Forged in the fires of high performance engines, Fel-Pro performance head gaskets are quite literally created to tame the fiery combustion chambers of up to 1,000 hp engines. Reinforced with KEVLAR® fiber and engineered to give you a perfect seal that can withstand combustion pressures of 1,500 to 3,000 psi, these gaskets are bred for high performance. They have a conformable anti-stick coating—and are constructed with pre-flattened copper or steel rings to make these gaskets easy to install, while also giving them the strength to tame your beastly power plant. Their anti-stick coating ensures easy removal and cleanup on frequent rebuilds, but they also aid in micro-sealing minor surface irregularities. When rebuilding your engine, use the parts you wish were in it to begin with. Put a set of these Fel-Pro performance head gaskets in that engine--not only to help it perform better today, but to make your next engine project that much easier.

Great gasket for high horsepower

Great gasket for making good power. I have made over 1000 hp with these gaskets with no issues. The only complaint is that the gaskets are short towards the intake manifold area. You will need to use a sealer to prevent oil leaks in this area.

Fel Pro 1143 MLS head gaskets

I installed these on my Supercharged SBC 383 with the recommended RA on my AFR 220 (1112) heads. The Fel Pro tech support recommended a small dab of Permatex Ultra Black RTV at the edge where it meets the intake manifold (because apparently they are a tad short) which I did. Well apparently more than a small dab is required because no sooner than I fired it up I had a ton of oil leaking at the surface between the head and the block right where the head meets the intake. Note this was not at the intake or the distributor as these areas are dry as a bone. I also used Fel Pro 1206 intake gaskets and installed them as recommended with a dab of Ultra Black RTV at the corners and then a bead at the front and rear. There is NO leaking at the front what so ever. The leak is specifically at the rear driver's side cylinder head observed with oil tracer a black light, a mirror and a digital video inspection camera. This is another four to 5 hours of work plus the cost of another set of head gaskets....read more
